ABSTRACT

The present invention is related to an aqueous coloring composition for keratin fibres especially human hair. Accordingly the subject of the present invention is an aqueous hair coloring composition comprising at least one hair dye and at least one color effect pigment consisting of synthetic mica coated with metal oxide or oxides and having a volume particle size distribution in the range of 1 to 750 μm at a concentration of 0.01 to 10% by weight, calculated to total composition.

The present invention is related to an aqueous colouring composition forkeratin fibres especially human hair.

Hair colouring has been widely practiced for ages. The colorations aredivided into two main groups, the first being permanent colourationbased on mainly oxidative hair dyes which penetrate into hair andpolymerize, and the second is based on direct dyes which is, withoutexcluding any penetration, mainly adsorbed onto hair and widely based oncationic and neutral dyes. In the latter, recently compositions based onanionic direct dyes have also been made available by the applicant whichdeliver brilliant, shiny and long lasting colours.

In hair colouration, one of the purposes is certainly change the haircolour and/or cover any inhomogeneous hair colours in particular greyhair. Another purpose is to refresh shine, brilliance and vibrancy ofhair colour. Especially in hair shine wide variability has been observedand there is, therefore, need for further improvements.

Compositions of the present invention can comprise UV filters forprotection of hair from environmental influences such as loss ofelasticity, loss of hair colour (bleaching effect of sun light). TheUV-absorbing substance is preferably selected from the followingcompounds: 4-Aminobenzoic acid and the esters and salts thereof,2-phenyl benzimidazole-5-sulfonic acid and the alkali and amine saltsthereof, 4-dimethyl aminobenzoic acid and the esters and salts thereof,cinnamic acid and the esters and salts thereof, 4-methoxycinnamic acidand the esters and salts thereof, salicylic acid and the esters andsalts thereof, 2,4-dihydroxybenzophenone,2,2′,4,4′-tetrahydroxy-benzophenone, 2-hydroxy-4-methoxybenzophenone andits 5-sulfonic acid or the sodium salt thereof,2,2′-dihydroxy-4,4′-dimethoxybenzophenone,2-hydroxy-5-chlorobenzophenone, 2,2′-dihydroxy-4-methoxybenzophenone,2,2′-dihydroxy-4,4′-dimethoxy-5,5′-disulfobenzo-phenone or the sodiumsalt thereof, 2-hydroxy-4-octyloxybenzophenone,2-hydroxy-4-methoxy-4′-methylbenzophenone, 3-benzyl-idenecampher,3-(4′-sulfo)-benzyl-idenebornane-2-one and the salts thereof and/or3-(4′-methyl benzylidene)-DL-campher, polysilicone-15. The preferredamount of the UV-absorber ranges from about 0.01% to 2.5%, morepreferably from 0.05% to 1% by weight, calculated to the totalcomposition.

The compositions of the present invention can comprise one or morehair-restructuring agents. The hair restructuring agents preferred areespecially the ones disclosed in the German patent DE 197 51 550 C2.Namely they are ceramide type of compounds, fatty acids and phytosterolor their mixtures.

Preferred ceramide compound is cetyl-PG-hydroxyethylpalmitamide.

Preferred fatty acids are those with 10 to 24 carbon atoms andespecially with 16 to 24 carbon atoms.

Sterols, especially the phytosterols, are as well preferred hairrestructuring agents as disclosed in the above mentioned german patent.Especially preferred ones are of plant origin for example ergosterol,sitosterol, stigmasterol, fucosterol, brassicasterol, fungisterol,campesterol, zymosterol, ascosterol, cerevisterol, episterol,faecosterol, spinasterol. Among those phytosterols, the ones found in“Avocadin” which is the unsaponified fraction of the avocado oil is morepreferred.

The concentration of ceramide in the compositions of the presentinvention can be in the range of 0.01 to 2% and especially 0.01 to 1% byweight calculated to the total weight of the composition. The fattyacids may be contained at a level of 0.01 to 2.5% and especially 0.01 to1% by weight calculated to the total weight of the composition.Phytosterol concentration of the conditioners is less than 1% andpreferably in the range of 0.01 to 0.5% by weight calculated to thetotal weight of the composition. It should be noted without limiting theuse of those ingredients the effect of those hair restructuringingredients is especially elevated when used in combination withpenetration enhancers.

The pH of the compositions according to the invention is in the range of2 to 11 in the preferred embodiment of the present invention, pH of thecompositions comprising only direct dyes and used without mixing with anoxidizing agent is in the range of 2 to 7, preferably 2.5 to 6, morepreferably 3 to 5. On the other hand, when a composition is mixed withan oxidizing agent independent from its content in terms of dyestuffs,preferred pH range is between 5 to 11, preferably 6 to 11, morepreferably 6.8 to 10. pH of the compositions can be adjusted by usingany organic and/or inorganic acids and alkalizing agents such asammonium hydroxide and monoethanolamine or their mixtures.

Composition of the present invention can be used as it is or aftermixing with an oxidizing agent. In case that the compositions of thepresent invention is mixed with an oxidizing composition prior toapplication onto hair, lightening (highlighting) and colouring isachieved at the same time. The oxidizing agents suitable are hydrogenperoxide, urea peroxide, melamin peroxide or perborate salts. The mostpreferred is hydrogen peroxide, which is used as a lotion containing 2to 12% by weight, calculated to composition only comprising hydrogenperoxide.

The new composition as a result of mixing colouring and oxidizingcomposition allows achieving simultaneous lightening and coloring. Themixing ratio of the colouring composition and oxidizing compositionshould be in the range of 4:1 to 1:4, by weight, preferably 2:1 to 1:3by weight.

Colouring and highlighting with compositions of the present inventioncan be carried out in several different ways.

One of the processes is that colouring composition of the presentinvention is mixed with an oxidizing composition and applied onto hairand after a processing time of 5 to 45 min at a temperature of 20 to 45°C. and rinsed off from hair.

Another way of carrying out highlighting and colouring is that of twostep application. In the first step, composition comprising at least oneoxidizing agent is applied onto hair and left on the hair for 5 to 45min and without rinsing off, the colouring agent is applied onto hair inthe second step and after processing additional 5 to 45 min the mixedcompositions are rinsed of from hair.

In the above mentioned two step colouring and highlighting process,between the application of first and second agents, the hair can bewashed with water and optionally hair can be dried.

In the lightening and colouring process using the colouring compositionof the present invention, the lightening can as well be carried out witha composition known as bleaching agents. For such a process suitablebleaching composition is for example the one disclosed in a EuropeanPatent No 560 088. Preferred way of carrying out lightening an colouringusing bleaching agents is two step process as mentioned above wherein ableaching composition comprising at least one bleaching agent is mixedwith an oxidizing agent and applied onto hair, after processing time of5 to 45 min rinsed off from hair and colouring composition of thepresent invention is applied and after processing tome of 5 to 45 minrinsed off from hair.

Furthermore, compositions of the present invention can comprise allsubstances customarily found in such preparations. Examples of suchsubstances are complexing agents, preservatives, fragrances, andantioxidants such as sodium sulfit.

Compositions of the present invention can be in the form of a thinliquid, emulsion, thickened liquid and gel. In the case that thecompositions are in the form of a thin liquid, it may be that metaloxide or oxides coated synthetic particles are precipitated orflocculated so that should be used after uniformly distributing theparticles in the composition by agitation for example shaking. In such acase it should also be possible to mix metal oxide or oxides coatedsynthetic mica particles prior to application onto keratin fibres withan aqueous composition comprising at least one hair dye.

Accordingly, another subject of the present invention is process fortreating keratin fibres especially human hair wherein synthetic micacoated with metal oxide or oxides with a volume particle sizedistribution in the range of 1 to 750 μm is added into the compositioncomprising at least one hair dye prior to application onto hair.

Following examples are to illustrate the invention but not to limit.
